"I suspect Jess would have done a SW degree. Once she'd graduated, she would be eligible for registration as a social worker"
I'm not 100% sure, but I don't think UG SW degrees existed when Jess was 18. They were only introduced in 2003 (I only know because DD2, born 1985, was one of the earliest to do one).
Before that I think there must have been diplomas and/or on the job training followed by a masters.
So what did Jess do at uni & how did she qualify in USA/Canada?
More (standard) poor research by TA, I fear
